    3. Weed suppression: Bulk bags can be used as weed suppression mats, which helps to prevent weeds from growing in garden beds and landscaped areas.
    4. Tarps: Bulk bags can be cut and sewn into tarps, which can be used for a variety of purposes, including covering outdoor furniture, protecting tools, and shading plants.
  3. Benefits of upcycling bulk bags: Upcycling bulk bags provides several benefits, including:
    1. Reducing waste: Upcycling helps to reduce waste by converting waste materials into new products.
    2. Reducing cost: Upcycling cuts down on the need to purchase new products
    3. Save Resources: Less new products means less resources are consumed

The Importance of Super Sack Recycling

Despite their numerous benefits, super sacks also pose a significant environmental challenge when it comes to disposal. If not properly recycled, they can take hundreds of years to decompose in landfills and pose a threat to marine life if they end up in the ocean.

Super sack recycling is critical in conserving natural resources, reducing greenhouse gas emissions, and minimizing waste in landfills. Recycling super sacks also creates a sustainable source of raw materials for the production of new products, reducing the need for virgin materials and contributing to a circular economy.

The Bulk Bag Recycling Process: A Step-by-Step Guide


At the start of the recycling journey, it’s crucial to gather the recyclable bulk bags. One of the most efficient and cost-effective ways of collecting the bags is through compacted bales. The bags must be sorted into three categories, namely Grade A, B, and C, based on their cleanliness and color. Grade A Sacs are immaculate and predominantly white with only colored stitching and handles. Grade B Sacs are somewhat dirty but still mostly white with some coloring. Grade C Sacs are excessively dirty or colorful.

Sorting and Cleaning

Given the wide range of industries and applications that bulk bags serve, it’s necessary to sort the bags into groups and clean them thoroughly based on their contents. The bags may hold everything from sand to hazardous chemicals, so proper cleaning is vital. During this stage, the recycling facility will also remove all zips and buttons.


Once the bags have been cleaned and prepped, they move on to the shredder, which size reduces them to small flakes. This stage makes the subsequent processes easier to handle and is a key step in the recycling process.


The shredded material goes through a separation phase, where machines sort the plastic based on color, shape, size, light absorption, and melting point. They also eliminate any impurities or contaminants from the polymers.  This is done through density separation and Infrared Sorting technology.  The more pure and uniform the flake the cheaper the separation phase becomes.


The final phase of the Super Sack recycling process is compounding, where the flake is melted into a finished product or reprocessed pellet. In this stage, extruders melt the shredded material at a temperature of approximately 240 degrees Celsius.  The molten plastic is then forcing through a screen to further filter out any remaining impurities.  Once absolutely clean and pure, the melted plastic is extruded into a strand, cooled and chopped, creating pellets or granules of the plastic. These pellets can be used in new products, such as clothing, playground equipment and packaging… even new PP Super Sacks. To enhance the pellet properties, recyclers sometimes add virgin resin, up to 50% of the blend, to strengthen the end result.

Challenges of PP Supersac Recycling and How to Overcome Them

Despite the many benefits they offer, the recycling of these bags presents several challenges that can be overcome with simple “best practices” of recycling.

Lack of Awareness

One of the biggest challenges facing PP Supersac recycling is the lack of awareness among users. Many people are unaware of the need to recycle these bags, or how to recycle them properly. This means that many bags end up in landfills, where they can harm the environment and wildlife. To overcome this challenge, education and awareness campaigns must be launched to educate the public about the benefits of recycling and the proper recycling process.

Limited Recycling Infrastructure

Another challenge facing the recycling of PP Supersacs is the limited recycling infrastructure. Not all communities have access to recycling facilities, and those that do may not accept these bags. To overcome this challenge, the industry must invest in new recycling technologies and establish more recycling facilities in communities where they are needed.

Contamination of Recyclable Materials

Contamination is a major challenge facing PP Supersac recycling. When bags are contaminated with other materials, they can’t be recycled and must be sent to landfills. To overcome this challenge, proper sorting and cleaning procedures must be established at recycling facilities to ensure that the bags are clean and free of contaminants before they are recycled.

Quality Control

Finally, quality control is a major challenge in the recycling of PP Supersacs. To ensure that the recycled material is of high quality, the recycling process must be carefully controlled. This includes proper sorting and cleaning, as well as monitoring the melting and compounding process to ensure that the final product meets the desired quality standards.
